Abstract
Methods for the generation and maintenance of transgenic tyrosinase mice
Steps
1.
Pronuclear microinjection of the human
tyrosinase complementary DNA fused to the rat tyrosine hydroxylase promoter into C57Bl6-SJL (RRID:MGI:5656718) mouse zygotes
2.
Selection of positive lines and backcrossing for 8-10 generations using
C57BL/6J mice (Charles River; RRID:MGI:3028467)
3.
Maintainance in heterozygosis by crossing heterozygous males with C57BL76J females
4.
Housed two to five per cage with ad libitum
access to food and water during a 12 hours (h) light/dark cycle (light-on 8
a.m.)
